Verigy V93000 Service Training Appendix B Autotransformer E8005A

Verigy Restricted Appendix B – Autotransformer Page 2 Power Options with Autotransformer The Autotransformer E8005A is required for systems with: Small or Large test head, if the primary voltage is 440V or 480V. Large test head, if the primary voltage is 200V/208V AND power consumption exceeds 36kVA. Currently this is the case if more than 42 digital channel boards (of any type) are installed. Analog boards can be neglected. 1 Additional Support Rack is equivalent to 5 channel boards. Example: For systems with 2 Additional Support Racks up to 32 channel boards are supported without the transformer. The E8005A can be pro-actively ordered for large test head systems to allow for later upgrades by ticking a checkbox in the configurator.
